    Alternative Curve Compression

    I did some tests with different high/low settings to see what kind of a difference each one made, however I didn't see any differences. Not to say there aren't subtle differences I can just not be noticing...

    Any thoughts?

    Also, I was looking at the alt_curve_c.gif that xvid includes... From that graph, I should think that anytime a file is reduced use High and use low if enlarged... am I assuming correctly?

    Curve aggression defines how quickly the codec adapts bitrate to frames. A high aggression will help the codec aid low bitrate frames while hurting high bitrate frames and is better for very dynamic scenes (i.e. a slow motion scene, then up to a lot of motion very quickly). Low aggression adapts slower and won't improve low bitrate frames as much, but will not harm high bitrate frames much either. Medium aggression is a compromise of the two.
    as haxed from doom9. Ok, so I was on the right track.

    Has anyone done any tests or noticed just how much slower or faster the bitrate adapts? Like I said, what I was testing wasn't much help =/

      I did not see much difference either.

      On a side-note, Koepi himself advises against using it, and I have since followed suit.
